Specification of Letters Patent.

Patented Jan. 8, 190'7.

provement on the device patented to lne August 15, 1905, No. 797,017, my present improvements being for the purpose of adapting my wall-plug to all the modern requirements.

In the.- advanced building requirements very little wood is used, so that the studding and furring are frequently not used, metallic lathing being employed and secured in position in various ways, and also the extensivev use of cement in monolithic structures has necessitated further improvements of my invention. Accordingly I have provided means in connection with my wall-plug for positioning and maintaining the same projected at the proper distance from the face of the wall for retaining metallic lathing and the like in desired position, my invention also including means for supporting the plugs in proper alinement while a concrete wall, for instance, l is being laid. In further explanation of the latter feature the common practice at present is irst to pour the cement between the boards or forms which are prepared therefor until the wall has been built up and then dig holes in the wall for receiving the wall-plugs,

which are then cemented in the said holes.

This is not only expensive and tedious; but it isl difficult to get the plugs located in proper alinement, depth, &c.

My invention enables the builder to place the plugs properly with great rapidity when the frame or molding-frame is being set up, so that the plugs aremolded directly into the wall as the latter is built up.

Further details of my 'invention will-.bepointed out in the course of the following description, reference being lad to the accompanying drawings, in which I have shown a preferred embodiment of my invention.

In the drawings, Figure 1 is a plan view of one form of' my plug.` Fig. 2 is a longitudinal section thereof, taken on the line 2 2, Fig. 1. Fig. 3 is a transverse sectional view i l netting, or the like when lsecured in place by on the line 3 3, Fig. 2. Fig. 4 is a sectional shows in side elevation a portion of the supporting cleat or plank used in connection with the wall-building form.

'I provide the pocket 1 with an extension 2, which projects beyond the previous terminal of the old style of plug, and at the point where the previous plug would have terminated I provide laterally-projecting ears 3 4, preferably formed by striking them up from the sides of the plug, thereby forming alined openings 5 for a purpose presently to be described, and at the eXtreme outer end I provide broad lateral flanges 6 7. The latter are not bell-shaped, as heretofore, but are bent as nearly at right angles as possible, so as to provide a broad bearing-surface especially adapted to support metallic lathing, wirea nail or staple held by the plug; The flanges 3 4 and openings 5l are located adjacentA the opposite edges of the plug, so as to leave a'.

wide intermediate space 8 of metal for receiving and guiding the nail which is driven lengthwise into the plug for holding purposes. I prefer to employ one set-of lateral flanges 3 4 at each side of the plug, although I do not limit myself in this respect.

Referring now to Figs. Land 5, where I have illustrated the method ofkbuilding a monolithic or concrete structure, it will be understood that opposite boards are formedv with an intervening space between them to constitute the opposite sides of the trough or 4form into which the cement 9 is poured. As -A these boards are being placed I interpose at the proper intervals a narrower board or cleat 10, or else similarly cut away the top board at that level, so as to provide a led e 1.1, having a width corresponding to the istance it is planned to have the wall-plugs project from the walls 12, and cut proper notches 13 in this top board or plank to receive the projecting portion 2 of the wall-pocket. In these notches 13 the successive wall-plugs are placed and secured in rigid position by nails or tacks" 14driv'en through the holes 5, so that allthe wall-plugs which are to be used in the building are thus put in place in the proper alinement and at the various positions desired before thecernent ior concrete has been poured. The result isthat when the cement is poured it flows around the vwall-plugs and theyare firmly embedded therein in exactly the correct position at the very start, thereby entirely eliminating all of view illustrating lthe manner of use.

crete and brace'the plug,` likewisegiving a finished appearance, &c. When the cement has set, the boards 10 are taken away in usual manner, the tacks being removed, and

the lathing or whatever other structure is to be secured to the plugs is nailed in place in usual manner, being held thereby at the proper distance from the Wall without any j .intervening studding., furring, or the like In the case of wire lathing the holding-wire 1 is passed through the holes 5 for securing the lathing in place against the outer end of the lug. There may be any number of holes 5, ocated anywhere in the part 2.

My invention greatly facilitates the economical and rapid construction of modern reinforced concrete buildings.

One decided advantage of my invention is that it does away with the necessity of using a metallic furring-strip in the ordinary bric and steel construction. It is applicable-as well to ,ordinary wall construction of all kinds and is used quite largely in floor constructions.

Having described my invention, what I claim as new, and desire to secure by Letters Patent, is-- 1. A Wall-plug, having lateral projections adjacent its frontend for engaging the front surface of the wall, and an extension projecting therefrom provided with means for encompassing and holding a retaining-nail at a distance from the wall and means for sugiporting the secured object remote from t e 4o Wall.

2. A Wall-plug, having a -lat body provided With laterally-projecting ears extending from the body of the plug near to but back from the outer end for mamtaining said outer end projected beyond the Wall proper, said outer end containing means for grasping a nail'when driven into it endwise.

3.1 A Wall-plug, having laterally-projecting ears extending from the body of the plug ad- Lacent to but back from the outer end for olding the outer end projected beyond the `Wall proper, and provided with transverse holes through the body of the plug between said ears andthe outer end, said outer end containing means for grasping a nail when driven into the plug endwise.

' 4. Awall-plug,havinglaterally-projecting ears extending from the body of theI plug adjacent the outer end for holding the outer end projectedy beyond the Wall proper, and provided with transverse holes between said ears and the outer end,l and supportingflanges extending laterally from the extremity of said outer end.

5. A Wall-plug, provided at and near to its outer end with pairs of parallel alining means for temporarily positioning the Wall-plug in the course of forming concrete buildings.

6. A Wall-.plughaving parallel engaging and alining means at its outer end beyond the body portion of the plug to beembed'ded in concrete, combined with .a supporting-board lilving means for holding said outer end rig- 1 y.

In testimony whereof I have signed my name to this specification in the presence of two subscribing Witnesses.
